2.2.5 Tamper detection

The product allows detection of state change on the tamper input of each channel (rising edge detected on the input normally held to ground).
The product wakes up regularly (according to the periods defined in registers S332 and S334) and checks the status of the tamper input of each
of the channels having active fraud detection.
The tamper alarm is stored if there are several successive detections (configurable in registers S333 and S335) and transmitted within the next
daily frame.
The alarm is automatically deactivated after the daily frame is sent.
The settings associated with this mode of operation are:
• Enabling and Configuring inputs (register 320)
• Fraud detection period 1 (register 332)
• Threshold for fraud detection 1 (register S333)
• Fraud detection period 2 (register 334)
• Threshold for fraud detection 2 (register S335)
